Best Debt Funds — Ranked by Returns
Debt funds lend to governments and companies for steadier, lower-risk returns than equity. Useful for short-to-medium goals and to balance an equity-heavy portfolio.
Debt funds lend your money — to the government, banks and companies — and pass the interest through to you as NAV growth. The label covers sixteen SEBI categories with genuinely different risk, from overnight funds that barely move to gilt funds that can swing several percent when interest rates shift. Picking well is mostly about matching a fund's two risk dials, duration and credit, to your actual time horizon.
The two dials: duration and credit
Duration risk is sensitivity to interest rates. When rates fall, existing higher-coupon bonds become more valuable and long-duration funds rally; when rates rise, they fall. The longer the average maturity, the bigger both moves.
Credit risk is the chance a borrower does not repay. Government securities carry effectively none; AAA corporates very little; lower-rated paper pays extra yield precisely because default is a real possibility. A debt fund's return should be explained by these two dials — if a fund's yield looks too good for its category, one of the dials is turned further than the name suggests.
Matching category to horizon
A practical map by how long the money can stay invested:
- Days to months — overnight and liquid funds.
- 6-18 months — ultra-short and low-duration funds.
- 1-3 years — short-duration and corporate bond funds holding high-grade paper.
- 3+ years with a known end date — target-maturity funds, which hold bonds to a set year so rate swings fade as maturity approaches.
- A deliberate rate bet — gilt and long-duration funds; zero credit risk, maximum rate sensitivity.
How debt funds are taxed now
For investments made after 1 April 2023, debt fund gains are taxed at your income-tax slab regardless of holding period, with no indexation benefit, as per current rules — effectively the same as FD interest. Verify the prevailing rules before filing. The remaining edges over an FD are flexibility (redeem any amount, no penalty), no TDS on gains for residents, and gains being taxed only when you actually redeem.
What to check before buying
Read the portfolio, not the past return: the credit-rating split, the average maturity and yield-to-maturity, the expense ratio (costs bite hardest where returns are modest — see why), and the fund's behaviour during 2018-2020, when credit events separated careful managers from yield-chasers. Filter all of this in the screener. Debt funds are lower-risk than equity, not risk-free; read scheme documents carefully.
Frequently asked questions
Are debt funds better than fixed deposits?
Post-2023 taxation removed the old tax edge, so it is now a practical comparison: FDs give a guaranteed rate with exit penalties; debt funds give market-linked returns with full flexibility and no TDS on gains for residents. For short horizons a high-quality liquid or ultra-short fund is a genuine FD alternative; neither is universally superior.
Can debt funds give negative returns?
Yes, in two ways — rising rates can push long-duration and gilt fund NAVs down for months, and a credit default marks down whatever the fund lent to that issuer. Short-duration, high-credit-quality funds keep both risks small.
Which debt fund is best for 6 months?
Horizon-first logic points to liquid or ultra-short duration funds holding top-rated paper — categories designed so that neither rate moves nor credit surprises should meaningfully dent six months of accrual. Compare candidates in the comparison tool.
